Final Step- Finding your App or Activating your Theme
Applications: In the case of an application or game, typically an icon will be installed onto your homescreen. On older devices the icon for the new application will appear on the main homescreen, or on newer devices the icon will appear in your downloads folder by default. You can also relocate the placement of this icon. Note that some applications may not install an icon anywhere, but rather will add more functionality to the device (a new option will appear on the main Options menu).
Themes: Unlike an application, when you install a theme it does not install any sort of icon onto the homescreen. Rather, you need to enter the Themes menu, which can be found by going to Options > Themes. Here you can select your new theme and activate it.
